PRINTING ATTACHMENT FOR ROLL-PAPER RACKS OR HOLDERS.

SPECIFICATION forming part of Letters Patent No. 636,154, dated October 31, 1899.

Application filed September 19, 1898. Serial No. 691,368. (No model.)

To all whom it may concern:

Beit known that I, JOHN W. LUKE, a citizen of the United States, residing at Oklahoma city, in the county of Oklahoma and Territory of Oklahoma, have invented certain new and useful Improvements in Printing Attach ments for Roll-Paper Racks-or Holders, of which the following is a specification.

The present invention relates to a device that is adapted to be attached to the rack or other device by'which a roll of paper is supported in such manner that it may be unrolled as it is wanted and that is provided with means for printing an advertisement or other matter on the paper as it is unrolled. Heretofore devices of this class have been provided with means for attachment to the rack, a type-roll, means for pressing the type-roll against the roll of paper, an ink-roll, means for pressing the ink-roll against the type-roll, and sometimes a cap or hood arranged over the inkroll. I do not therefore claim, broadly, as my invention an 'attachment having these features, my said invention being limited and confined to certain hereinafter-described improvements in an attachment having them or some of them whereby certain specified objects are accomplished.

The invention consists in the features of novelty hereinafter fully described.

In the accompanying drawings, which are made a part of this specification, Figure l is a side elevation of an attachment embodying the invention, a fragment of a roll-paper rack to which it is attached, and a fragment of a roll of paper. Fig. 2 is a plan View of the attachment itself. Fig. 3 is an elevation of some of the parts thereof viewed in the direction of the arrow 3, Fig. 2.

A represents the top rail of a roll-paper rack, and B a portion of a roll of paper so supported thereby that it may be unrolled as it is wanted for use.

0 is the supporting-bar of the printing attachment. It is designed to be attached to the rail A or to some other suitable or convenient part of the rack or holder, and to this end I may use a clip D. When a clip is used, it is preferably integral with the bar G, its two jaws being adapted to receive the rail A between them, and one of them being provided with a threaded opening, through which passes a clamping-screw E.

I F are spring-arms'proceeding from the bar 0 and engaging a hood or housing G, arranged over the type-roll H and the ink-roll I. These arms are preferably both formed of a single piece of spring-wire having portions f f coiled around the bar 0 and a straight portion f connecting the portions f f, the bar, being provided with a shoulder 0, upon which the portion f bears, whereby the coiled portions ff are prevented from turning around the bar.

The housing may be of any desired material; but I prefer to make it of Wood and substantially as shownthat is, with a flat top g, two flat sides g, disposed in planes that are parallel with each other and perpendicular to the plane of the top, and a cleat or brace g.

The spring-arms F are preferably passed through perforations in the brace g" of the housing, so that they have sliding engagement therewith; This is necessary by reason of the fact that as the paper is used the roll B be comes smaller in diameter, and all parts of the housing will move in a true circle around the portionsj' of the hangers, but the movement of the arms F of the spring will not be in a true circle around this center, for the reason that the coiled portion of the spring is constantly relaxing and increasing in diameter. Aside from this, the sliding connection between the spring and the housing is desirable, for the reason that it makes it very convenient in assembling or separating the parts.

The housing is kept from slipping off of the spring-arms F and connected to the bar 0 by means of a pair of hangers J, each of which consists of a piece of heavy wire, the ends of which project laterally. One of its laterallyprojecting ends j occupies a socket in the end of the bar 0, so as to be capable of turning therein, and the other, 3', passes through an opening in one of the sides g of the housing and into a centrally-disposed socket in the end of the type-roll, so that the roll is capable of turning thereon. By this means the type-roll is j ournaled and the housing is swung from the bar 0, so that the spring-arms F may hold the type-roll in contact with the surface of the constantly-diminishing roll of paper. It is found that the friction of the ends jj with their respective sockets is sufficient to hold the hangers in place.

The ink-roll I is provided in its ends with sockets, into which project the ends of a piece of wire which is bent to form the journals for the ink-roll and a bail or handle. The portions 70 of the wire form the journals of ink-roll. They occupy open notches g in the sides 9 of the housing and are engaged by springs L, by which they are held down with a yielding force, whereby the ink-roll is held in contact with the type-roll. One side 9 of the notch and the under side of the spring L when the latter is not under tension converge, so as to facilitate the insertion of the journal into the notch and beneath the spring. The portions 7a of the bail proceed parallel with the sides of the housing, and the portion 70" crosses the top of the housing and is engaged by a pivoted latch M. The advantage of the bail is that it enables the ink-roll to be removed, reinked, replaced, and otherwise handled with facility and Without soiling the hands.

An important advantage of the general construction and arrangement of parts above described is that they may be easily and quickly taken apart for being cleaned or repaired.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. In a printing attachment of the class described, the combination of a supporting-bar having sockets, a type-roll having sockets, a pair of separate and independently-removable hangers each having a laterally-projecting portion occupying one of the sockets of the type-roll and a laterally-projecting portion occupying one of the sockets of the supporting-bar, and a spring exerting its pressure in one direction against the supportingbar and in the other against the type-roll, substantially as set forth.

2. In a printing attachment of the class described, the combination with a supportingbar, a type-roll, having centrally-disposed sockets, and a housing, having openings in its sides, of hangers supported by the supporting-bar and having laterally-projecting portions passing through the openings of the housing and entering the sockets of the typeroll, and a spring'for holding the type-roll against the roll of paper, substantially as set forth.

8. In a printing attachment of the class described, the combination With a type-roll, means for supporting it,-means for pressing it against the roll of paper, and a housing, of a removable ink-roll having journals supported by the housing, a bail proceeding from said journals and disposed upon the outside of the housing, and means for holding the bail in place, substantially as set forth.

4. In a printing attachment of the class described, the combination with a type-roll and means for supporting it, of a removable inkroll, having journals, a part having notches occupied by said journals, and springs engaging the journals, the notches and springs having converging portions, substantially as set forth.
